If two-point charges, 2000 meters apart, have charge values of 40 C and -40 C, respectively, what is the value of the mutual force between them? (Coulomb's constant = 9.0 x 109 N•m2/C2).
Answer:
The value of the mutual force between them is 3.6 x 10⁶ N
Step-by-step explanation:
Given;
distance between the two-point charges, r = 2000 m
the value of the two-point charges, q₁ and q₂ = 40 C and -40 C
Coulomb's constant, k = 9 x 10⁹ Nm²/C²
The value of the mutual force between them is calculated by applying Coulomb's law;
[tex]F = \frac{K|q_1|q_2|}{r^2} \\\\F = \frac{(9 \times 10^9)(40\times 40)}{(2000)^2} \\\\F = 3.6 \times 10^6 \ N[/tex]
Therefore, the value of the mutual force between them is 3.6 x 10⁶ N.

if two successive discount of 50% are offered on a LCD TV with MRP of rupees 40,000 then find the price offered to the customer....... please tell me,,,,
Multiply the original by the first 50% discount:
40,000 x 0.5 = 20,000
Now multiply that by the second 50 % discount:
20,000 x 0.5 = 10,000
The price would be 10,000 rupees
Answer:
Step-by-step explanation:

What’s the equation of the line in slope intercept form
Answer:
y = 1/7x + 3
Step-by-step explanation:
Graph
P1(-7,2)
P2(0,3)
m = y2-y1/x2-x1
m = (3-2)/(0-(-7))
m = 1/0+7
m = 1/7
y - y1 = m(x-x1)
y - 2 = 1/7*(x -(-7))
y-2 = 1/7*(x+7)
y = 1/7x+7*1/7+2
y = 1/7x+1+2
y = 1/7x+3

The triangles shown are similar. What is the value of x?
Answer:
x = 10
Step-by-step explanation:
The bigger triangle is 2 times larger than the smaller triangle meaning all of the value of the smaller triangle are 2 times smaller than the bigger triangle and the bigger triangle is 2 times larger than the smaller triangle
Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{6}{3}[/tex] = 2 ( multiply both sides by 5 )
x = 10
(No links please) There were 2 red marbles, 3 blue marbles and 5 gold marbles in a bag.
You pulled out 1 red marble and did not replace it. Find the probability of drawing a gold marble next.
Answer:
5/9
Step-by-step explanation:
You started with 10 marbles total. You removed one marble and did not replace it, so you now have 9 marbles. The marble that you removed was NOT a gold marble, so you still have 5 gold marbles.
This means that out of the 9 marbles that you have left, 5 of them are gold.
This means you have a 5/9 chance of drawing a gold marble next.
What is the slope-intercept form equation of a line that has a slope of 1 and passes
through the point (-4, 10)?
Answer:
y = 1x+14
Step-by-step explanation:
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Substitute the point into the equation
10 = -4+b
Add 4 to each side
10+4 = -4+b+4
14 = b
y = x+14

Answer:
39
Step-by-step explanation:
sin^-1(x)= 39/62
x= 38.97
x=39
Solve x + 5x – 14 = 0
Answer: x = 7/3
Step-by-step explanation:
You join the X’s first which will give you
6x-14 = 0
Then you move the 14 to the right
6x = 14
Then you dived them and it give you 7/3

(X-3)^2=25 i need to find all the solutions to the equation
Answer:
x = {2, 8}
Step-by-step explanation:
(x - 3)^2 = 25
Take the square root of both sides
x - 3 = ±5
Add 3 to both sides
x = ±5 + 3
x = 5 +3 = 8
x = -5 + 3 = 2
x = {2, 8}
Answer:
x = 8, -2
Step-by-step explanation:
[tex](x-3)^2=25[/tex]
[tex](8-3)^2=25[/tex] Substitute x for 8 the subtract 8 - 3
[tex](5)^2=25[/tex] Multiply 5 by 5
[tex]25=25[/tex]
[tex](x-3)^2=25[/tex]
[tex](-2-3)^2=25[/tex] Substitute x for -2 then subtract -2 - 3
[tex](-5)^2=25[/tex] Multiply -5 by -5
[tex]25 = 25[/tex]

Answer:
(12, 12, 156) and (9, 9, 162)Step-by-step explanation:
Since AB = AC and the triangle is isosceles:
∠ABC ≅ ∠ACB3x² - 2x + 4 = 9x - 63x² - 11x + 10 = 0x = (11 ± √(121 - 4*3*10)/6x = (11 ± 1) / 6x = 2, x = 10/6The angles:

find the value of x HELP PLS
Answer:
x=45
Step-by-step explanation:
both angles are opposite angles with the same measurements
Set your formula up as
x+30=2x-15
30=2x-15-x
45=x
Now substitute 45 in place of x
x+30
45+30 = 75
2x-15
2*45-15 = 75
2x - 15 = x + 30
2x - 15 + 15 = x + 30 + 15
2x = x + 45
2x - x = x - x + 45
x = 45

Answer:
The mean is 6.
Step-by-step explanation:
To find the mean you need to do the following.
first, add up all the data to get a total.
next, count the amount of data you have.
lastly, divide the total by the count.
Answer:
6
Step-by-step explanation:
our given database is
2,3,6,6,7,8,8,8
first:add up all data:
[tex] \displaystyle \rm2 + 3 + 6 + 6+ 7 + 8 + 8 + 8[/tex]
[tex] \displaystyle = 48[/tex]
next:count the amount of data:
[tex] \displaystyle \boxed{ \begin{array} {ccc} \text{we have two 1 time} \\\text{we have three 1 time} \\ \text{we have six 2 times} \\ \text{we have seven 1 time} \\ \text{we have eight 3 time} \\ \hline \text{total} \quad \quad8\end{array}}[/tex]
Last:divide the total by the count:
[tex] \displaystyle \frac{48}{8} [/tex]
[tex] \displaystyle = 6[/tex]
hence,
the mean of the database is 6
